To all whom it may concern-.-

Be it known that I, Tuottns Varrcu, a citizen of-the' United'States, andresident oithe city of New York,

and State of New York, have invented certain new and useful Improvemeiusin Internal-Combustion Engines, of which the following is aspecification.

One of the desirable features in high-speed engines is a simple andeilicicut mechanism for reversin? the engine in as a short as possiblespace of time. Numerous experiments have been made in solving thisproblem, most of which were dciined to retaining the unidirectionalrotation of the driving ele- Inents, while providing devicesfor-reversing the rotation of the driven elements, requiring, of course,rather complicated mechanical arrangen-ren'ts, which in the inoin'ent oioper ation Were subjected to a tremendous strain, causing them notinfrequently to get out of order and, therefore, seriously to interferewith the reliable Working of the entire engine.

It is the object of the present invention to utilize a device, otherwisewell known in the art as such, in an improved and modified form, whichseems to represent. the most simple solution of a problem, whichhitherto has been thought to be one of the most com-- This solutionconsistsin the application to said use in a gas engine of the combustiontype, of a inultiple way valve, capable of suitably connecting the usualcoinbustion chamber take-inland exhaust either '35 to the mixing chamberor to the open air and thereby reversing the function and operation ofthe said take-in a nd exhaust. in addition to this feature,-the newmultiple-way valve is also provided with a passage or by-pass.

capable of directly interconnecting the take in to the exhaust of thecombustion chamher and causing therebyn cessation of the explosions and,consequently, a gradual slowing down of the engine, which etl'ect may belama-deuse of in restarting the engine and re- Versing its o eration bystill further operating tlie'mu tiplevalve, so that connections with theinlet and outlet are reversed, as

' well as the direction of rotation of the entire engine.

ltis obvious, of course, that in order to revcrse the direction ofrotation of the engine,

in the county of New York it is necessary to advance or reset thesparkplug in the proper direction.

The new device is applicable to }.)o \'crengines of any suitable type,in which case the inlet and outlet take the place of thetako-in andexhaust cl an explosive engine. The illustratioi'is, shown in theaccompany inn drawings, representative of one form of the presentinvention, and Figure l illustrates a perspective side view of theentire engine, having embodied therein the new multiplc-valve, whileFigs. 2, 3 and l illustrate vertical cross-sections of the valve indiilcrent positions, and Fig. 5 a vertical 61 05msection in a plane atright angles to the plane of the sections shown in Figs. 2, 3 and 4.

The perspective elevation, shown in the drawing, indicates at 1 theusual cylinder of an engine of the iour-cycle combustiontypc, supportedon a suitable base. i

2 is the piston connected by means of a piston-rod 3 to the crank l ofthe driving, shaft 5. i 6 is the. combustion-chambcr, having an inlet'or take-in 7, capable of being closed by a valve 8, which is operatedby means of the valve-rod 9 and the roller 10 from the valvecam 11,keyed to the valve-shaft 12, driven by means of intermcshing gears-13and 14 from the driving shaft 5.

'An air-valve 15 operated by means of the-valve-rod 16 and the roller 17from the valvccam 18 on the shaft 12, is located in an air-pipe,connecting an air tank or container to the combustion chamber. The checkvalve 19 prevents the return of the compressed mixture of gas and airfrom the combustion chamber.

An outlet or exhaust 2O 01 the combustion chamber 6 is connected bymeans oi suitable pipes to a muffler or the open air. It is capable ofbeing closed by a valve 21, operated through t'VulVLflOd 22 and a roller23 iron'i a valve-ca1n E l. An igniting device or spark plug 25 isoperated by a connecting rod 26 and roller 27 from a cam 28 on the shaft12.

The take-in 7 and the exhaust '20 are connected to pipes 29 and 30, thecontinuation of these pipes are shown at 31 and 32, and the connectionbetween the pipes isbroughi about by a multiple-valve nu-zchanism. Thisinechanisnicomprises a casing 33, contain ing a valve-body 34, rotatableon a shaft 35 by means of a lever 36. The valve-body 34 is provided witha set of assages or paths, capable of interchangeably connecting the tothe mixing chamber and the open air, re-

spectively, either by" straight or by crossconnect1on,orbyinterconnection; For this purpose the" valvebody 34 contains a set i oftwo passages l'e'ad-ing'in a straight line at right angles to the axisof the valve-body,

so that 1pissage '37 may directlyand n a stralght e connect pipe 30 topipe'32, and passage 38-1nay connect pipe 29t0 pipe--31;

' A second set of crosseconnections is capable of making the. followingconnections H-By means of-passage39, a connection between the pipe 29and 32, and by means of the pas- .device, represented by the air-Va ve15 and compressed chamber by .cam 18, while at any other cycle ofrotation this valve wi a container of compressed air, not shown in thedrawing, will be eflicient in two different ways, In the first Way, as aselistarting de-- vice for the engine, in-which case it is obvious thatin an engine of the four cylindertype, only one of the cylinders of theengine wil be in condition to receive a air passing into the combustionopening a hand operated valve, leading to the compressed aircontainer,This will start the engine, and as compressed air is supplied to each ofthe other cylinders until an ignition takes place in their com--bustion-chambers, the engine will finally-be brought to its vfulloperation. The second-function of they compressed air supply is, to actas a substitute for missed explosions, in which case it takes the placeof the explosive mixture after ignition and causes an additional impulseto the operating piston. It is obvious, of course, that the pressure onthe tank side of the check valve 19 must always be greater than the oneon the combustion-chamber side of this valve. As this valve isconstructed to open toward the combustion chamber, air can beadmittedionly when the valve 15 has been opened through the operation ofthe valve- 1period of the 1 be closed.- The use of the multi le-wayvalve in reversing the direction o rotation of theengine must'bepreceeded by first cutting out the ignition device and closing the handoperated valve of the compressed air container, the lever 36 is then setso as to bring the lay-pass 41 in, operation, whereby the ally is ressedair charge of explosive 'mixture,- drawn in through the acting throughandpassed 05 by the by-pass 41 to the combustion-chamber. spark plug 0take-in. 7, is simply communicated 1 the acting exhaust 20, and ledagain into When now the erating' cam and the com pressed-air va veoperating cam is properly to cross-connect the pipes 29 and 32 and thepipes 30 and 31,- as shown in Fig' 4, the hand operated air-valveleading to the air tank is opened again,

becomes now while" the exhaust 20- becomes, the acting takein, theoperation of the valve 15 remains the same, the igniting device 25.
